GMAT Prep

Ya I remember the Boxed ones... Solved it here recently but could not find the post

[9] = 3*9 = 27 as 9 is odd we have to get 3m here
[6] = 1/2 * 6 = 3 as 6 is even so we have to get 1/2 m here

now [9]*[6] = 27 * 3 = 81

81 is exact value but what will be the boxed value?

The [odd] = 3*odd = 81

When we convert odd to Boxed odd we need to divide the value by 3
Thus 81 = 3*(81/3) = [27]

when m is odd (=9) ( now 9 is m and m is odd)
the first (9) =3*9=27 ( sorry, i cant drawn the square but i hope you get what i am typin)
the second (6)=1/2*6=3 ( now 6 is m and m is now even)
27*3=81
we see each answer choice... we saw that 27 is odd and 27*3=81
so the answer is (27)
hope it helps

Thank you for your answer.

I just don't understand how I know to multiply 9 by 3 and 6 by 1/2. What I did wrong, is that I divided 9/3 and 6*2. Don't see the pattern of how to know if I should multiply or divide..

What is the question asking? [9]*[6] =?

There are two conditions given in the Question and FIRST one is as follows:

When the m inside the box (i.e. [m]) is odd the you multiply 3 to the m.
We can write [m] = 3m when m is odd.

Now what is 9: odd or even?

Of course 9 is odd then we apply the Odd condition what the question has given us.

[9] = 3*9 = 27 .

Does this make sense? Yes or No let me know? If Yes the you can find out how [6] became 3.

Dear Shovan,

I understand how to get to 81 but I don't get why we should divide it by 3 after? I got the answer 81... also what is the boxed value? Shouldn't the answer be 81 because we applied the rules the question provides to [9]x[6]?

Yes my dear friend you get 81 is absolutely correct. But see the option do you have 81 or boxed 81 [81].

If u take [81] then according to the rule the absolute value is 81*3 = 243.
But what is our absolute value of [9]*[6] = 81

So how will you get absolute 81? When you take boxed [27], which is equal to absolute 81.

Hope this helps

Thanks Shovan for explaining! Now I need your help over here: https://www.beatthegmat.com/easy-questio ... 68824.html

Thanks for posting such a Good question.
They have made a trap my putting value in [ ]
If they didn't put the [ ] answer must have been 81.

Thanks Guys,
Its good to be familiar with the traps of GMAC

friends why do we need to reach to 81 ?

simply multiply 9*6= 54
m=54 ... thats even.
so m/2 = 54 / 2 =27
